Here is a R32 numbered 3610 on the F line, serving Neptune Avenue bound for Coney Island Brooklyn. The F is no longer using these cars.
Here's the B train in Brooklyn at Avenue J bound for Brighton Beach. This is a temporary platform on the Manhattan bound Express track.
The R32s are in the midst of retirement, they have been around since 1964. These trains were running on the B and F lines and I took them last year.
